Ultrafast lasers are an ideal choice for Nitinol stent micromachining and are widely used for this purpose.
The near-diffraction-limited optical beam delivery yields a focused spot size optimized to machine small features. The short pulse dynamics of ultrafast lasers machine the Nitinol with minimal thermal stress or damage to the substrate.
We recommend the aeroPULSE FS50 or the ORIGAMI XP-S.
